PLUMBERS FURNACE.

Application fried rgbmgry 25, i924. serial No. seams.

State of Illinois, have inventednew` and useful Plumb'ersr-Furnac-es,ofwhieh. the following is a specification.

This invention relates to new and useful `improvements in a plumbersfurnace, with special reference to economy in the construction,convenience inthe handling, and safety in the operationl thereof.

'One of the specific vobjects of the inventionlis to provide means forcatching fuel which may overflow from the priming` pan, thus4preventingv'it from'flowingdown the sides ofthe'tanlr and possibly4causing. a dis as trous fire` yForftliis.purpose, eti/depression is"iiorn'iedA in the upper face ofthe tank, which also provides a seat fort-hespring which holds the priming pan and the shield or flueinoperative position.

Another, object is to provide an improved supportingvmeans for the ladleandl soldering iron, in combination with improvedk means forattachingand supportingathe bail, ,which 1s a. further insurance againstaccident.v

` still further object of the invention is t@ prende improved meaneff,Supper-tine theY priming pan and theshield or fluefin:

ysuch a manner as to insuresuiiicient air for combustion, yet efectuallyprotecting the flame from wind or draft. Y' Also the rangement of thesupporting means is such as to facilitate 'the' disassembling ofthevari-V ous parts for cleaning or replacing them'.

The essential principles of the invention and its advantages 'willbemorefully eX- plained in connection with the accompanyits preferred form.

In the drawings: Figure 1 is a side View partly in elevaeral assembly ofthe'. furnace l n Figure 2 is aplanyiew thereof.

Figure 3 is. a front elevation of .the invention.

"The `tank lOis also provided. with `a fuel pipe1'? through whiclrtlie passageof thev fuel is controlled yby means of asuitable valve 18. The fuel line includes a T19 to which is connected aheating. coil 2O locatedcentrally above the tanklO, and terminating atits lower end in an elbow 21 to which is connected a burner. tube 22,having a vent 23 through fuel is emitted! A priming pan 211 is `locatedbeneath the .coil`2'0 andY fuel Vvent 23', 'and' has aA central `tankand. soiling the Hoor, or possibly resulting in va 4disastro us fire;The` depression 27,'of course, 1s of greater diameter than lthe primingpan 211, and serves also as a seat for the lowerk endof the coiiedspring26. relfe-his spring serves normally to holdk the priming pan upagainst the'burner tube 22, but maybe easily Vco rnpress,ed when it isdesired :to remove the priming pan, andto disassemble they other partsof Athe furnace.

Initsfnormal position, the, priming'pan 241 is .yeldely' held 'bythes'pifiney@ against theburner tube/2 2 andthe cylindri ycal shield orflue28, the lower end of which is held withinthe Harige forming`the'periphery of the pan. The shield 28 vhas an elongated opening v29 atone side, which receives the burner. tube22, and also serves to admitsufficient'- air. for .the complete combustion of the fuel, while theyremaining portion of theshieldis imperforate and effectually protectsthe flame againstf wind or e e El e e draft. manner ofattaching theibail, and` its'relaiThe ladle holder 30 is'provided with a plurality oflaterally extending ears' 31, .which are perforated to'k receive the:upper ends `of posts 32, andare secured theretoby bosses 34, extendingupwardly from the tank l0. The ladle holder 30 is open at its bottom,where it is provided with a circular integral flange extendingdownwardly, and constituting a top rim for receiving and retaining theupper end of the shield 28. The ladle holder 30 provides a support forthe soldering iron, and its lower portion is provided with inwardlu'projecting lugs 36 adapted to support the ladle. The upper end of theshield 28 is provided with notches 3.7, adapted to receive the loweredges of the lugs 36.

The upper portion of the ladle holder 30 is provided with twodiametricallj.7 opposite ears 38, which are located in rear of two ofthe El, and are adapted to receive the looped ends 39 of a bail LlO. Thesides of the bail, adjacent the looped ends 39, are offset inwardly,shown at ll, so that the bail when lowered to one side ma'v rest on theupper ends of the adjacent posts 32, as shown in Figures 2 and el. rlhebail when in this position extends nearliT in a horizontal plane, andmav be used as a support for the handle of the soldering iron. lllhenthe bail is svvung over to the opposite side of the furnace, it willdrop downwardlyv out of the walv.

ln the operation of nrv improved furnace a small amount of liquid fuelis first allowed to flow into the depressed portion Q5 of the primingpan, and is there ignited. rlhe coil quickly becomes heated7 andthereafter theV vaporized fuel is ignited as it leaves the veut Q3, aswill be understood by those familiar with the art. ln case the fueloverflows from the priming pan 2d, it will collect in the depression 27in the top of the tank l0, so that there is no chance of its runningdown the sides of the tank and saturating the f-iurrouuding objects. Thedepression Bfr also forms the seat for the spring 26, which holds thecup 5.24- and the shield 2S in operative position. Bv compressing thespring` Q6, however, the cup may be readili,7 lov. red and removed aswell the shield 2l, whereupon the other parts of the furnace may beeasili7 taken apart. The shield 2S is formed with an opening 29 in oneside on v, which is a great advantage when the device is used wherethere is considerable wind or draft. The location of the filleropeningin the bottom is a further insurance against lire since it isimpossible to lill the tank without extinguishing the lflame. The ladleholder 30 and the upper rim 35 of the shield are made in one integralpiece and the bail is connected near the upper edge of the ladle holder,so lthat the furnace maybe easily carried with a ladle full of moltenmetal without any danger of its tipping over. The manner of connectingthe bail is also of great advantage, since the bail may be used tosupport the" handle of the soldering iron when the latter is beingheated.

lfrhile l hare shown and described in considerable detail the specificfeatures of the invention, it is to be understood that these. aremerelj,Y illustrative, and that many' niedliications ma.v be made in thevarious details of censtrurtion, size, and relative location of thevarious parts without departing from the salient features of theinvention, or sacrificing the advantages thereof.

that is claimed is:

l. ln a plumbcrs furnace, the combination of a fuel tank, a ladle holdersupported above the tank, apriming pan and shield.r and yieldable meansfor supporting said pan and shield beneath the ladle holder with theshield 'in contact therewith7 the upper surface of said tank having adepression underneath the priming` pan for catching any overflowtherefrom, said depression forming a seat in which said vicldable meansis supported.

2. ln a plumbers furnace, the combination of a fuel tank, a ladle holdersupported above the tank and having means for supporting a ladle, aburner beneath the ladle holder, a shield for the burner, and means foryieldably holding the shield in contact with the ladle holder.

3. In a plumbers furnace, the combination of a fuel tank, a ladle holdersupported above the tank and having` means for supporting a ladle, aburner beneath the ladle holder7 a shield for the burner having an airopening on one side only, a circular flange integral with and dependingfrom the ladle holder and normally receiving the upper end of theshield, a priming pan normally receiving and supporting the lower end ofthe shield, and means for yieldably holding the pan and shield in theirnormal positions.

4l. In a plumbers furnace, the combination of a fuel tank. postsextending upwardly therefrom, a ladle holder supported by the posts,means for supporting a ladle within the ladle holder, a pair ofdiametricallv opposite earsv extending` from the ladle holder in rear oftwo of the posts, and a bail pivotally connected to said ears and havinginwardly offset portions adapted, when the bail is lowered to one side,to rest on the upper ends of said two posts, whereby the bail becomes asupport for the handle of a soldering iron resting in said ladle holder.

5. In a plumbers furnace, the combination of a fuel tank, a ladle holdersupported above the tank, a priming pan and shield, and yieldable meansfor supporting said pan and shield beneath the ladle hol der with theshield in contact therewith.

6. In a plumbers furnace, the combination of a fuel tank, a ladle holdersupported above the tank and having means for supporting a ladle, abmnei' beneath the ladle holder, a Shield for the burner, a pliming pansupporting the lower end oi' the shield, and means i'oi yieldablyholding` the shield in Contact with the ladle holder.

7. 1n a plumbers furnace, the combination of a fuel tank, a ladle holderSupported thereon, a burner beneath the ladle holder, a priming panbeneath the burner, a depression formed in the top of the tank forcatching ofei flow from said pan, and yielda'ble pan supporting meanshaving a portion disposed Within said depression.
